This paper pushed the boundaries of aspect-oriented programming (AOP), by investigating it for the development of multiagent systems. It presented a first empirical quantitative study on AOP beyond the scope of conventional crosscutting concerns, such as persistence and distribution. The work is published in a respected journal, and has already 55 citations (GoogleSchoolar). It has also led to follow-on activities including co-chairing of workshops at ICSE, the leading conference in software engineering.
